To all whom c'zi may concern: oration proof. The socket is formed with Be it known that I, WALTER G. BROWN, a a tapering inner wall surface, which is citizen of the United States of America, and broken at diametrically opposite points by resident of Nevada, Story County, Iowa, inwardly-extending lugs l5, 16. the former have invented a new and useful Filling bein formed with an upwardly-extending Means for Gasoline Tanks, of which the folhinge-member l7 and the latter being formed lowing is a specification. with a step or shoulder 18 and with taper- An object of this invention is to'provide ing walls.

I claim as my invention 1. In filling means for gasoline tanks the coi'nbination of a tank having a filling port and a flanged collar on said tank surrounding said port with a socket adapted to be screwed in said collar, said socket being formed with a tapering inner wall, the bore thereof having its largest diameter outside said tank, and a wicket member hinged to the screw socket and opening outwardly of the tank and also formed. with a tapering outer wall mating said tapering inner wall, said wicket member being formed with a peripheral flange overlaying the wall of the 15 socket.

2. In filling means for gasoline tanks, a screw socket formed with a tapering inner wall and also formed with lugs, a Wicket member hinged to one lug and formed with a notch adapted to receive the other lug and formed with a tapering outer wall coacting with the tapering inner wall, and a latch connecting said socket and wicket member, a portion of said wicket member overlaying the wall of the socket.

Signed at Des Moines, in the county of Polk and State of Iowa, this 9th day of June, 1921.
